a paratus for seaming bags and conveying t e same to a suitable position where they may be taken away.

It also, as a part of the apparatus, includes cutting mechanism for severing the chain of stitching between. successive bags, after which the bags pass upon the conveying belt and are carried away to a suitable place.

In the form shown, the invention comprises primarily a supporting framework, upon which are mounted a series of sewing heads, and in rear of the table is an endless -vconveyer, WllllG located between the bed plate of the sewing mechanism and the conveyer is a series of stationary upright pieces or plates, so arranged with respect to the sewing mechanism as to receive the seamed bag and deliver it in a substantially vertical position, so that its edge shall come in contactwith the conveyer belt, which latter by reason of its movement and the friction of its surface against the sack, will give to the latter a complete turn, so that the sacks are delivered to the conveying belt with the under side of the stitches showing, thus facilitating the work of the inspector in examination of the sewing. It is also intended to use in conncction with each sewing head, an automatic cutting device for severing the chain of stitching between any two sacks, but this cutting mechanism is not herein claimed speciiically, but only as a part of the complete apparatus.

The invention also contemplates the use of deflectors arranged at any desirable intervals along the conveying belt, so that if the apparatus is used upon different sizes of bags, by arranging the deflectors between any two sewing heads, the bags of different kinds will be forced off the conveying belt and-delivered in suitable piles. Y

The invention also consists in various matters hereinafter described and referred to in the appended claims.

In the accompanying drawings which illustrate the invention, Figure 1 represents in outline a top plan view of the apparatus embodying my invention; Fig. 2 is a front elevation of the same; Fig. 3 is an end elevation of the same; and Fig. 4 is a detail view iilustrat-- ing a form of cutting mechanism used in con nection with the sewing heads to sever the chain of stitching between any two successive bags.

In those drawings, A represents the table .or supporting framework, which is of any suitable construction, and has the usual line shaft B. Upon this table are supported in the usual manner, any desirable number of sewing m'achines of the usual bag sewing type, these being marked C. The belt wheels of the sewing machine are connected up with a line shaft in the usual manner;

As shown in Fig. 4-, I use in connection with each sewing machine a cutting apparatus for severing the chain of stitching between any two successive bags. This cutting apparatus comprises, as herein shown, a continuously running knife member operated from the main shaft of the sewing machine in any suitable manner, and cooperating with a stationary member.

The cloth plate of the sewing machine has in rear of the needle and feeding mechanism, an elongated slot, so arranged that when a bag is fed off from the machine, the chain of stitching will be drawn into the slot 1 in the cloth plate, and into the path of movement of the knife blades sever the chain. This particular form of cutting device fornis no partof the present invention, but is s mply shown by way of illustration, and as forming an important feature in the combination. It is, however, shown described and claimed in an application filed by Dudley S.-Seym0ur, Jan. 1906,'Serial Journaled upon the framework or upon the floor, if desired, are rollers'D over which is or framework, and extending downwardlyfrom the level of the sewing mechanism to a point a suitable distance above. the upper between it and the succeeding bag 2, 3, the knife blade operating tosurface of the conveying belt and outwardly to a point substantially over the central portion of said conveying belt, is a series of standards or upright frames E, the upper surfacesof which are so arranged with re- I spect -to the bed plates of the sewing maines that when the bag has been seamed, ,vill feed off on to one of the uprights or ndards E and fall off to one side vertically, that its edge will rest upon the conveyer belt and extending substantially transversely across the belt. The friction of the conveyer belt against the edge of the sack, will cause the latter to be pulled along underneath the. standard. The part which was uppermost during the sewing operation is now faced down upon the conveying belt with the under lines of the stitching exposed, so that the inspector will be able to tell without lifting up the bags and turning them over whether the work has been done properly.

In connection with an apparatus of this character, it is sometimes desirable to use certain of the sewing heads on one kind of work, and'others upon other kinds of work, and to arrange for the delivery from the conve 'ing belt of sacks of different character at di 'erent points, I have )rovided removable deflectingplates F whic are formed to lit suitable supports G on the stationary frame. These deflectors are arranged on an incline across the face of the belt, and when the sacks are drawn against them by the movement of said belt, they are forced off on to the fioor into a rece )tacle prepared for th ir use.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is

1. In apparatus for seaming bags, the combination with a sewing mechanism, of means for inverting the bags'after the sewing operation substantially as described.

2. In apparatus for seaming bags, and conveying them away, the combination with a sewing mechanism, of a conveyer, and means interposed between the conveyer and the sewing mechanism for inverting the bags; substantiallyas described.

3. In apparatus for seaming bags, the combination with. a sewing mechanism, a

member to receive the seamed bag, and invert it, and mechanism for severin the chain of stitching between successive )ags; substantially as described.

4. In apparatus for seaming bags and conveying them away, the combination with a sewing mechanism, of a conveyer, a stationary member to receive the seamed bag, and deliver it in inverted position to the conveyer; substantially as described.

5. In an apparatus of the character described, sultable sewing mechanism, an automatic cutting device for severing the chain of stitching between successive bags, a conveyer, and means between the conveyer and the cutting mechanism for inverting the bags; substantially as described.

6. In apparatus for seaming bags and conveying them away, the combination with a sewing mechanism, of a conveyer, a stationary member to receive the seamed bag and deliver it vertically to the conveyer, the movement of the conveyer causing complete inversion of the bag substantially as 'de-' I scribed.

7. In apparatus for sewin bags and conveying them away, the com ination with a sewing mechanism, of a conveyer, a member to receive the seamed bag and deliver it in inverted position to the conveyer, and means for deflecting the bags from the conveyer ,substantially as described.

8. In apparatus for seaming and delivering bags, the combination with the sewing mechanism, an endless conveyer, a vertically arranged bag guiding apparatus between the sewing mechanism and the conveyer, .so arranged with respect to the sewing mechanism as to receive the bag, and deliver it with its edge in contact with the conveyor, whereby the movement of the latter will cause acomplete inversion of the bag; substantially as described.

9. In apparatus for seaming and delivering bags, the combination with the sewing mechanism, an endless conveyer, a vertically arranged bag-guiding apparatus between the sewin r mechanism and. the conveyer, so arranger with respect to the sewingn echanism as to receive the bag-and deliver it" with its edge in contact with the conveyer, whereby the movement of the latter will cause a complete inversion of the bag, and deflecting
